ABSTRACT:
Polymers are rendered more oxidatively stable by reaction with an antioxidant or stabilizer, generally a vinyl-group- or thiol group-containing antioxidant, in the presence of a free radical which may be produced by a redox system or ultra-violet light. The resulting polymers can be used as such or can be used as additives in other polymers to stabilize the latter.
